EXCLUSIVE: Ultra-wideband radio has been heralded as the solution for “relay attacks” that are used to steal cars in seconds. But researchers found Teslas equipped with it are as vulnerable as ever.
Couldn’t a Model 3/Y owner also just disable the phonekey and use the NFC cards? NFC only broadcasts a few inches right? I would think that would be VERY hard for a malicious actor to capture with relay/replay attack.
Following that, is it possible to use the Phonekey only in NFC mode or is it always broadcasting on Bluetooth LE and NFC?
